SPECIFICATION forming part of Letters Patent No. 343,977, dated June 22, 1886.

(No model.)

.To @ZZ whom it may concern:

Be it known that I, GEORGE H. BALDWIN, a citizen of the United States, residing at Grand Summit, in the county of Cowley and State of Kansas, have invented certain new and useful Improvements in Broom-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a perspective view of my improved clamp; Fig. 2, a front elevation, partly in broken section, of the staple-driving device; and Fig. 3, a detail View, partly in section, showing the stapledriving 4 device in position in the slotted jaw of the clamp and the staple in position to be driven. l

The present invention has relation to that class of broom-machines provided with means for compressing the broom into a flat form for the purpose of stapling; and the object thereof is to improve the construction, whereby the stapling of the broom is greatly facilitated and the machine simplified and rendered more t certain in driving and clinching the staples, and the machine, as a whole, capable of being manufactured at a comparatively small cost, to bring it within the reach of those requiring the same. These objects I attain by the construction substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A B represent, respectively, the upper and lower arms of a clamp', thelower one being stationary and secured to a suitable base or support, C. The upper arm, A, of the clamp at one end is hinged to the arm B, and at the opposite end has a transversely-slotted jaw, D, and the lower arm a transversely-grooved jaw, E, the slot a and groove b being on the same vertical plane when the two jaws are together upon the broom. The upper arm of the clamp, which is movable, is operated by a cam-lever,

F, the cam thereof working in a guide-mortise, c, in said arm, and connected to the lower arm by links d, pivoted thereto and to the sides of the cam, as shown. After the arm A, with its jaw, has been pressed down, by means of the cam-lever above described, and

, released it is thrown back to its normal position by a suitable spring, e, one end thereof secured to the lower arm and the opposite or free end of the spring bearing against the under side of the upper arm.

'The arm A is guided in its movement by the guiderodsfand staples g, and the arm B has suitably connected to it aspring-gage, G, which projects from the sides of the arm and is bent so as to have its ends m extend inwardly over the jaw E.

The arms A B may be variously modified, also its attachments, and any preferred means may be employed for operating the upper one of the arms. Any changes coming within ordinary mechanical skill I reserve the right to make without departing from the principle of my invent-ion.

When the broom leaves the winding-machine, there is a series of bands of wire or twine around it, equal in number to the seams required, and when placed in the machine in position to drive the staples it is of course necessary that the band, in connection with the staples which are to constitute the seam, should stop exactly opposite and over the center of groove b in the jaw E, and iin attaining this object I have provided the gage G.

It should be understood thatwhen the broom is placed between thejaws D E it is of cylindrical shape, or round, being held in such shape by the bands of wire ortwine encircling it. VNow, these bands are movable on the broom, that they may be adj usted in the proper place to be secured by stapling, which is ac complished by the extremities of the ends m of the gage G catching over the band when the broom is placed in position, and bringing the band directly in line with the groove b.

As previously stated, the broom is round when first placed between the jaws of thef clamp, and when the upper jaw is brought down on the broom it attens it, and consequently increases in width by expanding laterally. To allow of this expansion of the broom the gage is made yielding, so that when the broom expands the ends m will be forced out laterally to give space between them for the increased width of the broom when compressed by the upper jaw of the clamp.

Vhen a broom is placed between the jaws IOO . the staples vertically while being clinched on the concave surface formed by the groove b of the jaw E, thereby preventing the natural inclination of the staples while being clinched from bending sidewise or backward, and admitting perfect work being done. The vertical grooves h may be of anysuitable size and number to adapt them to the size ofthe staple used, as well as the number employed to form the seam in stapling brooms of different sizes and also whisks. l

The punch K is held within the casing by stops k at the ends thereof, a coiled spring, Z, around the shank of the punch, forcing the latter back in position, to beagain used to drivek the stapies after a new set has been placed in the groove h.

After the staple-driving device has been 3o- Having now fully described my invention,

whatI claim as new, and desire to secure by Letters Patent, is-

In a broom-machine, the combination, with a suitable staple-driving device, of a clamp consisting 'of a stationary and a movable arm provided, respectively, with gro'oved and slotted jaws, and means for operatingthem,and a spring-gage having inwardly-bent ends eX- tending over the groove in the lowerjaw, and operating substantially as and for the purpose set forth.

In testimony that I claim the-above I have hereunto subscribed my name in the presence of two witnesses.

GEORGE H. BALD\VIN.
